SKB503 is an advanced nRF52840 chip solution Bluetooth 5.0 module. It is suitable for ULP wireless applications and for connected devices throughout the Internet of Things.

It is designed ready for the major feature advancements of Bluetooth® 5 and takes advantage of Bluetooth 5’s increased performance capabilities which include long range and high throughput modes.

The SKB503 is ready to take advantage of the considerable performance improvements for Bluetooth low energy with the arrival of the Bluetooth 5 specification.

The 802.15.4 PHY and MAC layers are supported natively on the SKB503. This allows nRF52840 to be used in a wide range of home and industrial sensor network applications as it supports two of the most popular wireless sensor standards in use today, Bluetooth low energy and 802.15.4 derivatives. This adds to the already existing radio support for Bluetooth low energy, ANT/ANT+ and 2.4GHz for proprietary.
